"I mean, it was just a candy store for me," she said. "I had so much fun playing her, and I wish I could've gone on playing her, because she was really fun. I love to play those absurd women. And I got to sing with James Taylor! If nothing else, I got to do that."

She added: "I had a great time. I'm sorry and sad it didn't go, but geez, I'm glad I got to do that."

Janney also praised her co-star Matthew Perry, who executive produced the show, and described him as "pretty great to work with".

"I applaud him," she said. "He was wearing so many hats. I could see it was exhausting him and yet he really cared about this, and really put his heart into it. I just admire him for it and applaud him. I could never do it in a million years, so I think it's admirable. He really held it together and did it, writing and rewriting while we were doing it. He did a great job. I'm proud of him."
